3. CALCULATIONS. 



For calculation of the effect of lack of uniformity of the magnetic field 

 upon the deflection see W4(426). For experimental method of inte- 

 grating non-uniform field see Tm3(565). 

 Velocity of Rays, from simultaneous magnetic and electrostatic deflection 

 using formula (13). 



Maximum velocity is a function of the cathode fall and varies from 

 10^ to 2 X 10' cm. (15,000 v.): W3(449) ; Evir3(3o6) ; Ws(56i, 263); 

 Tm3(57i) ; cf. Ew2(soi) ; Ewi(i86). 



Maximum velocity for voltages above I5>ooo v. is 2 x 10'' cm. ; 

 W5(56i, 263) ; Tm3(57i) ; Tm8(668). 



Velocity approximately the same for all the rays of one kind, as shown 

 by the shape of the deflection streak: Ws(s6i, 261); W6(588) ; 

 Tm3(569); W8(664) ; Sti(686). H rays have velocity) '2 times 

 that of H2 rays.
